Arrgh!

71-72 really is okay. If it drops past that, you might want to throw a blanket over the tanks (you're using a UTH, not a lamp?) But at 72F they can thermoregulate just fine, they'll just hang out mostly on the warm spot.

The cinny might be "whistling" not wheezing. Some snakes do it around shed time. My black pastels do it ALL the time. They whistle when they're annoyed at me, they whistled when they're excited, they whistle when they do any climbing or crawling at all. It's surprisingly loud! I took them both to the vet, he did a mouth check, and there were no signs of an RI. So I guess it's just the shape of their nasal passageways? Maybe it's the single-gene version of the duck-billing you see in the black supers?

To be safe, you should either take the cinny to the vet, or do an oral check yourself. Get a good grasp on the cinny's head/neck, take a q-tip, hold it sideways, and push the cinny's nose up until its mouth opens. Hold the upper jaw open with the q-tip, and have a look around--- mouth should look pale pink. White may mean anemic. Bright pink or red or any dark colors are bad. Wet is okay, but bubbles and drool are not.

You shouldn't hear any whistling with the mouth open, because the snake is mouth breathing at that point, not nose-breathing. Whistling at this point means trouble...

Then again, you may not notice, because if this is the first time you've ever done an oral check, there will be lots of thrashing and squirming to pay attention to! Which is why the vet may be the safest option. But I try to do oral checks once a year on all my animals. Older animals usually get the drift and start cooperating.
